T0 LU who/fn, t vnr/ty concern:

Be it known that I, ROBERT O. REDPATH, a citizen of the United States, residing in the county of Johnson and State of Kansas, have invented certain new and useful Improvements in Baling Attachments for Threshing- Machines, of which the following is a specification.

My invention relates to baling press attachments for threshing machines and has for its object to produce an attachment for baling the straw at the tail end of a thresher.

A further object is to produce means for automatically separating the straw into bales of predetermined length.

A still further object is to produce means for girding the bales with tie-wires and holding the wires in such position that they may be conveniently tied by hand. v

With these general objects in view the invention consists in certain novel and peculiar features of construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which- Figure 1, represents one side of a threshing machine or separator, equipped with an attachment embodying my invention, said attachment being shown in central longitudinal section. Fig. 2, is a horizontal section taken on. the line II-H of Fig. 1. Fig. 3, is a vertical section on the line III-III of Fig. 2. Fig. 4, is an inverted plan view with the baling case partly broken away. Fig. 5, is a vertical section taken on the line V*V of Fig. 3, but with the driving belt omitted. Fig. 6, is a sectional view of a portion of the apparatus to disclose the action of the mechanism for girding the bale with wire, taken on the line Vl-VI of Fig. 7. Fig. 7, is a rear view of the a paratus shown in Fig. 6. Fig. 8, is a verticalpsection on the vdotted line VIII of Fig. 1.

In the said drawings where like reference numerals designate corresponding parts in all the figures,-1 designates a portion of a threshing machine or separator of any suitable or preferred type, and 2 a boX or casing secured rigidly to its tail end in any suitable manner and forming practically a continuation of the thresher frame, the front and lower portion of the boX or casing underlying said frame in order that Athe rackl 3 of the thresher shall project into the casing and overhang the curved 'and transversely eX- I tending baling case 4, which case preferably projects beyond one side of the casing as at 5, and at the opposite side is provided with. an extension 6, preferably hinged as at 7, to the casing so that it may be folded up againstthe latter and secured in such position in any suitable manner when the apparatus is not in use, any suitable means such as a hasp 8 on the end of the balingI case extension and the staple and padlock 9 secured to the thresher frame, being utilized to secure said extension in its folded position.

The extension is practically a duplicate of the compression end of an ordinary baling case, being equipped with any suitable tension, not'shown, and with'longitudinal slots 10, for a purpose which hereinafter appears. It is also provided with spring catches or retainers 11, which yield as the condensed straw is being forced in the direction indicated by the arrow Fig. 2, and snap behind such'straw after thewithdrawal of the compression plunger hereinafter described, to hold such straw in its condensed position preliminary to the girding of the bale with wire, as also hereinafter described.

The baling case 4, is provided in its front side' with a horizontal slot 12, in which operates the horizontally swinging plunger arm 13, said `arm extending forwardly and being pivoted as at 14, to the threshing machine frame at the point where radial lines from the curved case 4 would intersect as will be readily understood. Near its rear end said arm as shown herein is bent slightly as at 15, in order that the plunger 16 secured thereto within the case may pass into extension 6, far enough to force the condensed straw within the sphere of action of catches or retainers 1l, without necessitating the slotting of the corresponding side of the casing as would be the case if the plunger arm was not bent. It is to be understood however, that the parts may be so proportioned as to avoid the necessity of bending said arm 13 -and yet permit the charge of straw to be forced the required distance into the extension without slotting the side of the casing. In the proportion shown it is necessary in order to withdraw the plunger into the projectng portion 5 of the casing, to 'slot the proximate side of the latter as shown at 17, Fig. 5.

The baling case 4, is open at its rear side as at 18, as shown clearly in Fig. 1, so as to provide a large feed opening through which IOO IIO

the charges of straw are 'forced'into the case by the feed plunger 19, said plunger bein f preferably hollow and adapted to pass baci-f and forth through the opening 20, in the rear wall of the box or casing, the latter at the rear margin of the opening being provided with a deflector 21, which tends to force the straw forward as it is discharged from the tail end of the thresher or separator in the usual manner, such straw as will be readily understood entering the box or casing and dropping downward therein, the rack 3V of the thresher or separator preventing any accumulation of the straw upon the baling case.

22 designates a frame secured rigidly to the feed plunger 19, and projecting rearwardly therefrom and pivotally connected as at 23 to the swinging skeleton frame 24, pivoted to brackets 25, secured to the upper* portion of the box or casing, the lower ends of said swinging frame being connected by retractile springs 26, to the cross bar 27, of the thresher or separator, Said ,cross bar may be the axle of said machine. These springs effect the feed or forward stroke of the feed plunger, The rearward or withdrawal stroke of the feed plunger is effected through certain instrumentalities actuated by the return stroke of the baling plunger and the means for actuating the latter is as follows :-28 designates a shaft preferably driven in any suitable manner, not shown, by the mechanism which operates the thresh ing machine cylinder, said shaft being `journaled in suitable boxings 29, secured to the top of the threshing machine, and said shaft is geared by wheel 30, and endless belt or connection 31 to the wheel 32 journaled upon stub shaft 33, also secured to said ma chine. -Said -wheel operates continuously in the direction indicated by the arrow Fig` 3,- Vand is provided at its outer margin with ay ange 34, and a wrist pin 35 projecting outward from the flange. It is also provided at its inner margin with a beveled tooth 36, adapted at times to engage and operate a jointed lever, consisting of the outer portion 37, and the inner portion 38, the latter being journaled on stub shaft 33, said portions being pivoted together to permit the outer portion to swing laterally at times.

39 is a segmental guide plate secured to the side of the thresher or separator and provided With a slot 40, of such length that its ends are diametrically opposite, the lower end of the slot being pitched as at 41, inwardly of the plane of its body portion as shown in Fig. 4, in order that lever portion 37, when engaging said pitched portion of the slot, shall be forced inwardly until even tually it is beyond the path of the tooth 36. A sprin 42 in the path of the lever is compressed y the latter in its movement through portion 41 of the slot so as to pe ready to start said lever on its reverse movement, at the instant its disengagement with the wheel tooth takes place. i The free or outer end of said lever has a swivel connection as at 43, with a cable 44, which cable is swiveled at its opposite end to the wrist pin 35. Between said points of attachment .it extends be tween guide rollers 45, then across the top of the thresher and the guide rollers 46 carried thereby, then down at the opposite side of the machine and under guide roller 47 supported from the box or casing as shown or in any other suitable manner, then transversely through the box or casing forward of the baling case, around guide pulley 48, between guide rollers 49. Between guide roller 47 and uide roller 48, the cable is rigidly attached to the plunger arm, preferably to the bracket 50 depending rigidly therefrom.

When the wheel and lever occupy the positions shown in Fig. 3, it will be seen that the wrist pin 35 is in the same plane as the guide roller 48 and the axis of the wheel, and that in consequencethe baling plunger will be disposed in the" position shown by dotted lines From the foregoing' it will be understood that when the parts mentioned occupy the position shown in Fig. 3, the lever is free to reverse its movement, which it does at the instant the wrist pin passes forward of the `plane hereinbefore referred to', moving backward at a speed corresponding to the rota tion of the wheel because of the connecting cable, and not at a greater speed becauseof the friction between the guide plate 39 and spring 51, carried by said lever. The spring 42 by assisting the lever on its return movement prevents any possibility of the latter becoming locked'in the position shown,be

cause when released, it roccupies the same plane with the wheel axis and the cable Where it passes between the rollers. 45. As the wrist pin passes the plane mentioned and the lever swings backward at a corresponding speed as stated, the plunger is caused lby the cable to make its power or compression stroke, this stroke as hereinbefore mentioned being sufficiently long to cause the plunger to advance the charge of straw beyond the catches or retainers 11, so that the latter will retain such charge. As this action takes place, the wrist pin has attained a position diametrically opposite to its original position, the lever has attained the position shown in dotted lines Fig. 3, and the tooth of the wheel has engaged the lever preparatory to moving it with and in the same direction as the wheel until it is again disengaged from said tooth as, at the time, and by the means indicated, this movement of the lever accompanied by the approach. of the wrist pin toward its original position effecting the return of the plunger te the opposite end of Ioo the baling case, as will be readily understood. .v

In order that .the movement of the baling plunger shall effect the rearward or withdrawal stroke of the feed plunger against the resistance of springs 26, the following construction is provided: 52 designates a pair of grooved wheels journaled at the bottom of the box or casing, and secured rigidly to and concentrically of said grooved wheels are disks 53 which in diameter slightly exceed the length of stroke of the feed plunger. The disks are linked by pitmans 54 with the cross bar 55 of swinging frame 24, the front ends of the pitmans being pivoted for vertical movement as at 56 to brackets 57 depending from the disks, theirrear ends being pivoted for lateral movement as at 58, to brackets '59,

pivoted for vertical movement on cross barI 55. By this arrangement the rise and fall of the cross bar as the frame swings back and forth and the lateral movement of brackets 57 due to the horizontal rotation of the disks is accommodated.

60 designates a cable engaging the grooved disks and extending from the front side of the left hand one to which it is rigidly attached at its end to the rear side of the right hand one. It engages the latter for approximately three-fourths of its circumference and terminates in a sleeve 61, having an upwardly projecting pin 62, which pin projects through the slot 63 of a cross bar 64, secured at its opposite side to the side walls of the casing in any suitable or preferred manner,

said pin above the bracket having an enlargement or head 65, to hold it in the latter and in the path of an arm 66 carried by the baling plunger bracket. Said slot 63 is of such length that the movement of the pin therein from one end to the other results in rotating the disk about one hundred and eighty degrees or half a circle and terminates at each end in a rearwardly sloping portion 67 into which the pin enters 'under the pressure of said arm 66 in order that disengagement between them may take place and leave the arm free to pass the pin in its further travel.

Secured to the slotted cross bar 64, at the end of its slot nearest the baling case extension, is a spring 68, which intersects the sloping portion 67 of the slot rearward of the pin when engaging said portion, the function of said spring being to force said'pin forwardly into the plane of the body of the slot after the arm 66, has automatically forced the pin therein and passed onward toward the baling .case extension, it being understood that by reason of the retractive action of spring 68, 'said pin stands at the junction of the body of the slot and said sloping portion when struck by said arm. Upon the return of said arm after the compression stroke of the baling plunger has been made, it engages the opposite side of the pin and forces I the same through slot 63, toward the opposite side of the casing, which action through the medium of cable 60 rotates the curved wheels and disks and therefore overcomes the resistance of springs 26 and effects through the mediumof the pitmanssthe withdrawal or rearward stroke of the feed plunger. Just before the -return stroke of the baling plunger is completed and at the end of the rear stroke of the feed plunger, arm 66 passes the pin by forcing it into the short sloping portion 67 of said slot, which action is instantly followed by the forward stroke of the feedplunger under the retractive action of said springs 26', as will be readily understood.

To guard against the possibility of straw getting into the baling case behind its plunger, I mount a spring roller 69, at the outer side of the box or casing and rearward of the baling case as show-n in Fig. 2, said spring roller carrying a curtain 70, mounted thereon like a 'window shade on the usual spring roller, and having one end attached to the rear edge of said plunger, a suitable opening 71, in the box or casing being provided for the curtain to pass through, and the guide roller 72 in said opening to reduce friction as far as possi-- ble. This curtain unrolls against the resistance of its spring as the power stroke of said plunger takes place and automatically rewinds as said plunger movement is reversed. The construction of the curtain and its roller is not detailed as they may be of precisely the same construction and relation as an ordinary shade roller and shade.

To prevent an overcharge of straw to the baling case, I provide a reciprocatory apron 73, of substantially the same area and form as and fitting flatly against the underside of the top wall of the baling case and in the same horizontal plane as the upper portion of the feed plunger, said apron extending through a slot 74 in the front wall of the baling case and having forwardly projecting arms 75, underlying guide brackets 76 secured to the inner sides of the casing, said guide brackets in conjunction with the guide slot 74 maintaining the apron in the horizon.- tal position described. j' The arms 75 are provided in their edges nearest the baling case extension with notches 77 and from said notches are beveled forward to their opposite edges as at 78.

Normally engaging the notches 77 are the upper ends of catches 79, pivoted to brackets 80, and having their lower ends pivotally connected by a link 81, spring 82 between one of the catches 7 9 and its bracket 80, serving to hold `the former yieldingly in the path of the beveled ends 78 of the arms.

Projecting from the link and depending into the path of the baling plunger arm is a hook 83, adapted to be forced through slot 17 of casing 2, by the plunger arm 13, on its return stroke, to trip catches 79 from engagement ICO ITO

with apron arms 75, to release the latter and permit it to be moved rearward as hereinafter ment of the latter terminates.

explained. The mechanism for effecting such rearward movement is as follo`ws:-Se cured to the 4underside and rear end of arms 75 are cables 86, which extend forwardly a distance greater than the width of the apron and around guide pulleys 87, suitably supported from the baling case, the opposite ends of said cables being connected by retractile springs 88 extending `forwardly below arms 75, and attached to pins 89 projecting inward from the sides of the casing 2, or the separator, if preferred. lThe hook 83 is disposed at such point on the link 81., that it is struck by the baling plunger arm on its return stroke just before the 'rearward movement of the feed plunger is ended, the result being the catches 79 are withdrawn from the notches 77 to permit the springs 88 to retract and incidentally slide the apron rearward so as to meet the feed plunger as the rear move- Instantly thereafter the feed plunger moves forward as hereinbefore explained so as to force the charge of straw into the baling case and at the same time force the apron forward to the position shown, the spring actuated catches I 79 automatically rengaging the notches and locking the apron in said position. The feed plunger as shown most clearly in Fig. 2, has its front wall corresponding in forni to the curvature of the baling case and consequently when advanced it forms the rear wall of said case during the entire power or compression stroke of the baling plunger.

90 designates a stub shaft depending rigidly from the bottom of the balng case extension, i and equipped with peripherally grooved pulleys 91 and 92, pulley 91 being embraced by a cable 93, secured rigidly to the pulley at one end as at 94 and connected at its opposite end by a retractile spring 95 to the outer end of said extension. Secured rigidly to said pulley 91 so as to rotate therewith is a double arm needle, the same com prising essentially the arm 96 projecting vertically upward at the rear side of the extension, the horizontal arms 97, projecting rigidly from vertical portion 96, and terminating in segmental arms or needles 98, of somewhat greater length than the width of the extension, said needles terminating in barbed ends 99, which are beveled upwardly from their points, and at their rear ends said barbs are preferably equipped with grooved rollers 100. Ordinarily the needles occupy the position shown in 'full lines Figs. 2 and 4, most clearly, the retractile spring 95, holding them in such position and returning them to such position `after each needle operation as hereinafter explained, it being understood in this connection that in such operation the needles pass through the baling case extension in the plane of the longitudinal slots 10,

, frame as shown most clearly in Fig. 3.

thereof, and between the bale and the box or casing.

101 designates a cable attached at one end to pulley 92, and at the other to a fixed point, such as pin 102, carried by the box or casing. Intermediate of the fixed points it is guided around a pulley 103, journaled on a bracket 104, secured by preference to the thregher t 1s also guided around a pulley 105 journaled on a pin 106, depending from the front portion of a jointed lever, said lever, consisting of a rear portion 107 pivoted for horizontal movement to a bracket 108, secured to cross bar 27, and a front portion 109 pivoted to the rear portion as at 110, for vertical movement. The spring 95 when holding the needles withdrawn as in Fig. 2, incidentally serves through the connections described tol hold the jointed lever 107-109, in the position shown in Figs. 2 and 4. The front portion of said lever extends through the horizontal slot 111 of a suitablebracket 112, secured to the box or casing, which-bracket extends concentrically of the pivot point of the jointed lever and is of substantially the proportion shown. The gravitative tendency of the front portion of the lever together with the downward pull thereon by cable 101, because engaging the pulley 105, at the lower side of the lever, tends to hold the front end of said lever portion depressed as shown in Figs. 3 and 8 most clearly. This depression of the front portion of said jointed lever is permitted because the lowerwall of the slot 111, slopes downward as at 113, at the end contiguous to the baling case extension. In thisconnection it will be noticed by reference to Fig. 1, that the extreme front end of said lever portion when depressed, is below the plane of'A IOO IIO

swing the jointed lever from the position l shown in full lines to the position shown in dotted lines Fig. 4. By the time said lever reaches said dotted position, it is Withdrawn from the path of said heel 115, leaving the plunger 'arm 'free to continue its movement in the direction mentioned. Said lever inthe movement, mentioned, through-the medium of its pulley 105 and cable 101',v rotates the needles from the position'shown in full lines Figs. 2 and 4 and dotted lines Fig'. 6, to the position shown in full lines in the last-named iigure, whenl their barbs underride the wires hereinafter described, until such'wires snap into the rollers 100, this action of the needles taking place as also shown in said last-named figure, while the bale is held from backward movement by the retainers 11, as hereinbefore explained. The instant this relation between the needles and the wires is established, which is at the same moment that the bracket heel 115, passes from engagement with the jointed lever, spring retracts and withdraws the needles to the position shown in dotted lines Fig. 6 and draws the wires looped around `the rollers 100, transversely through the baling case extension and against the rear end of the bale, see dotted lines.

116 designates the reels journaled upon a vertical shaft 117, carried by bracketI 118, secured to the side of the threshing machine, the reel shaft having'any suitable retarding means, to prevent it gaining momentum and paying out more than is required, the retarding means shown being a collar 1183, on the shaft, and a spring brake 119, frictionally engaging said collar and secured rigidly to the bracket. From said reels the wires extend rearwardly and aroundthe guide rollers 120, suitably supported from the box or casing contiguous' to the inner end of the baling case extension, and in the plane of the slots 10 thereof. From said guide rollers the wires, vin the initial part of the baling operation, extend diagonally through the'slots 10 in the same horizontal plane and are secured to the upright portion 96, of the needle frame. As the bale begins to form from successive charges of straw forced into the extension, it comes against those portions of the wires exten ding through the baling -case extension, after which each additional charge added to the bale effects the automatic paying out of wire from the reels. Eventually when the bale has attained its full length as indicated by the reference character 121, the wires will occupy substantially the positions shown in Fig. 6, that is to say, will extend from rollers 120, along the front side ofthe baling case extension, around the end of the bale and back to the upright portion of the needle frame.

The 'length of the bale is automatically determined by the following mechanism: 122 is a shaft journaled in bracket 123, carried by the baling case extension. on said shaft is a toothed wheel 124, projecting through the central slot or opening 125, in the front side of the extension and into the path of the bale so that as the latter moves outward while in course of formation, it rotates wheel 124, and therefore the shaft 122. The shaft carries a sprocket wheel 126 connected by chain 127 to an idler sprocket wheel 128, suitably supported, from the box or casingpreferably, and movable with said sprocket 128 is a second sprocket wheel 129, connected by 'chain 130, with an idler sprocket wheel 131, journaled on the same Mounted rigidly stub shaft 104, that carries the idler roller 103. This chain is provided at a suitable point with a depending V-shaped tooth 132, which once in each complete travel of the chain engages the upper edge of a lever 133, suitably supported as at 134 from the box or casing, said lever projecting transversely inwar l and under the depressed end of the jointed lever. The proportion of the parts just described is such that the V-shaped tooth 132 engages the lever 133 at the termination of one of the power strokes of the baling plunger so that the operation of said lever by said tooth shall raise the depressed end of lthe jointed lever into the path of heel as hereinbef-ore explained. As a result the first portion of the return movement of the baling plunger swings the ointed lever as hereinbefore explained and thereforel causes the needles to pick up the baling wires and `draw them .transversely through the balingv case extension rearward of the bale. Immediately after this takes place the attendant disengages the ends of the wire from the upright portion of the needle frame and then cuts the wire which is looped around the needle He then secures the first-named end of each wire the formation of the bale, the ends of the reel wires being left free because the next charge of straw clamps them tightly against the bale just completed, the clamping action being sufiiciently heavy to overcome the resistance of the reels and insure the paying out of wire therefrom as the formation of the bale progresses. Before the second bale attains its full length its front end has entered the contracted or tension portion of the extension and as a result the ends of the wires between such bale and the completed one in advance are clamped so tightly that they cannot slip when the needles again engage the wires and pull them tightly against and around the front side and rear end of said bale. In this connection it should be stated that the attendant has ample time to perform the operations just described because no further operation of the needlesV takes place until the wheel 124 has been rotated sufficiently tor again effect the raising of the depressed end of the jointed lever through the instrumentalities described. j

As the various operations have been described in detail it is thought that a recapitulation of the entire operation is unnecessary. It is to be understood of coursethat the invention is susceptible of modification in various particulars without departing from its spirit and scope or sacrificing any of its advantages.

Having thus described the invention what I claim as new and desire to secure by Letters Patent, is
